Practical Information-Flow Aware Middleware for In-Car Communication

Today's vehicles are increasingly connected to Internet, devices and integrate more and more electronic components. More than just ensuring their passengers' safety, which remains nevertheless one of their main objectives, cars have to deal with private information and encounters the same security issues as traditional computers. Until recently, automotive technologies allowed very little space for security, but the transition towards full Ethernet-based on-board network will change this situation. In this paper, we present solutions for decentralized information flow control in order to enhance the security and privacy level of the car data management. We describe the implementation of these mechanisms in an automotive middleware and propose its evaluation.
